Is pnumetic air powered, has sat in the bottom of the tool box for a while, when you pull the trigger is has a spindle that rotates and pushes out at the same time. Might be for some type of sir clip or rivet , NFI

Ahhhhh, thats why its in the bottom tool draw !

Thanks mineral

I was given a compressor recently with no tools so looking at buying stuff. I've noticed all the air tool kits have something you don't need. In the end I forewent the nibbler and got the air chisel/hammer. All I wanted was a ratchet and impact driver. It would of cost me 3 times as much just to buy them on their own as to buy a kit with unneccasary accessories. Go figure.

Must say though it was kinda satisfying air chiselling through a phone book in micro seconds!

Be very careful, it poops black holes

was gonna post a picture of my dick

They work really well and make lots of little moon shaped swarf, that attack and puncture bicycle tyres at every opportunity.
